The art is very beautiful and the story is melancholy but sweet. But idk I keep seeing parallels to itou-san which I think is a significantly better story.
I also don't quite understand the thing with the dad. So he just gave up on his son being an assassin or whatever the fuck they're supposed to be? Idk it's just so vague for no reason.
I like the style and tone of the story, but there are a lot of plot holes. It also does get a bit melodramatic
